This is driving me crazy. A user logs into my Facebook app, does some stuff. Then goes to Facebook and logs out. I've got a little timer that calls FB.getLoginStatus() every once in a while to see if the user is still logged in. But whenever FB.getLoginStatus() gets called it returns a response with a session object. WTF? Shouldn't it return undefined/unknown?
I'm using the absolute most basic call to Facebook evar:
FB.init({
appId: 'MY APP ID',
cookies: false,
status: true,
xfbml: false
});
FB.getLoginStatus(function (response) {
if (response.session) {
console.info("Session exists");
} else {
console.info("Session empty");
}
});
setInterval(function () {
FB.getLoginStatus(function (response) {
if (response.session) {
console.info("Session exists");
} else {
console.info("Session empty");
}
});
}, 10000);
I checked and double checked the permissions that are being requested with the allow. I am only requesting email and sms. So.... any advice?
don't do it in the hard way. This situation has a simple solution, just add a "true" statement as a second parameter from the getLoginStatus method:
FB.getLoginStatus(function (response) {
if (response === undefined || response.status === 'connected') {
// Do something after logout
}
}, true);
Just be careful and aware that every call to this function will make your App to go to Facebook's servers and can give you a considerable amount of network load depending on your implementation. Hope this helps!
I had the same problem using your code.
The only way I got round it so far is to initialise the sdk each time login status is queried:
setInterval(function () {
FB.init({
appId : 'xxxx', // App ID
channelUrl : 'xxxx', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
oauth : true, // enable OAuth 2.0
xfbml : true // parse XFBML
});
FB.getLoginStatus(function (response) {
if (response.authResponse) {
console.info("Session exists");
} else {
console.info("Session empty");
}
});
}, 10000);
In this way I always get the correct session status. If there's a more efficient way to do this please let me know!
Try initializating FB with
status: false
So it will work as you expect. It worked for me
Are you sure the session always gets destroyed when the user logs out? Maybe it's just a var inside the session that changes if the users logs in or out....?

Using the Facebook Graph API (v2.4), I can't seem to access any information about mutual friends, not even the total count.
Here's my graph query (User ID changed for privacy purposes):
https://graph.facebook.com/v2.4/123456789?fields=context.fields(mutual_friends)
The result I get is:
{
"context": {
"id": "dXNlcl9jb250ZAXh0OgGQBqWf9ZAHMZA1yjZBJZABsMDkDORNsle8wkS8Acci9r4FsOdyRVl1TSGSXAsofmlaWYS05piSZCV9F1QwNNs0L9XpNuGLAaLyMk8Fnaiwyxpm5shUZD"
},
"id": "123456789"
}
I tried using FB's iOS SDK to make the same query as well, but got the same result.
Any suggestions?
The all_mutual_friends, mutual_friends, and three_degree_mutual_friends context edges of the Social Context API were deprecated on April 4, 2018 and immediately started returning empty data sets. They have now been fully removed.
The {user_id} must be another user of your app, and the user access token you MUST use is from another user of your app.
Then
GET /{user_id}?fields=context{mutual_friends}&access_token={other_users_access_token}
should work and give results, if both users gave your app the user_friends permission.

The new Facebook graph api has divided friends into Friends & Invitable_friends .
me/friends/ returns my friends who are using the app while me/invitable_friends/ returns only the list of my friends who are not using the app.
But in my app,a user may interact with random users too who may not be on his friend list.
So how do i get user data for those who are using the app but are not on my friend list.
Thanks.
I went through the same issue and solved it like that: when a user starts your app by default you ask for permission to access his public profile information, which includes real ID, name and some other. You simply store the user data (id, name, etc.)in a database. This way you keep track of all the people using your app and they can interact with each other.
JavaScript Example:
window.fbAsyncInit = function () {
FB._https = true;
console.log('here');
FB.init({ appId: 'xxxxxxxxxxxxxxxx', cookie: true, xfbml: true, oauth: true, version : 'v2.0'});
Login();
};
function Login() {
FB.login(function(response) {
if (response.authResponse){
checkUser();
}
else{
console.log('User cancelled login or did not fully authorize.');
}
}
);
}
function checkUser() {
FB.api('/me', function(response) {
$.ajax({
type: "get",
url: "cgi-bin/checkUser.cgi",
cache: false,
data: {"user_name" : response.name, "u_id" : response.id, "link" : response.link},
success: function() //onSuccess,
{
console.log("user " + response.name + " checked!");
},
error: function()
{
console.log("Error with server connection on user checking");
}
});
});
}
I don't know in what language you are writing the app but I believe that in every language you should call the "login" function, which asks the user for permissions and basically gets access to info.
To get details of users who are using the app but are not your friends,call the following
graph.facebook.com/v2.0/
?ids={comma-separated-ids}&access_token=app_access_token&fields=name,picture
access_token is a must else graph-api returns following error-
The global ID xyz is not allowed. Please use the application specific ID instead.
This will work for all users who have authenticated the app no matter their authentication date,but for any non-app user graph-api returns above error message.
I added to phonegap app Facebook Connect,
It works fine and generates Access Token, But when I'm trying to get the userID the value is
"Undenified"
my function:
FB.init({
appId: "************",
nativeInterface:CDV.FB,
xfbml: true,
useCachedDialogs: false,
status: true,
cookie: true,
oauth: true
});
//alert("Init Done");
FB.getLoginStatus(function (response) {
if (response.authResponse) {
if (response.status == 'connected') {
Token = response.authResponse.accessToken;// This one is Good!
userid = response.authResponse.userID;// This one is Bad
}
I use the following and it works fine:
FB.api('/me', {}, function (response) {
fbuserid = response.userid;
});
This gives you the user data. You can also pass the scope just to get what you want like email, userid, etc...
Iterate through the keys to see what is stored
for (var key in response.authResponse) {
console.log(key);
console.log(response.authResponse[key]);
}
I have a difficult problem. Difficult means I searched through the net and StackOverflow as well the whole FBJS SDK documentation and haven't find answer.
I am building a Page Tab application where I'd like to let fans to rsvp events. So I have to check if the user is logged in and if it doesn't I have to login. That sounds pretty easy, but FB.getLoginStatus doesn't fires callback function. This is the code excerpt:
FB.init({
appId: window.appID,
status: true,
xfbml: true,
cookie: true,
oauth: true,
channelUrl: 'http://example.com/fb/channel.html'
});
and then I simply - of course after the user clicks on a button - call FB.getLoginStatus, but it seems it doesn't do anything.
I've already checked sandbox mode, FB.init success, URLs in application settings and developing environment. I can call FB.ui, although FB.ui with method: 'oauth' I get an error message saying " The "redirect_uri" parameter cannot be used in conjunction with the "next" parameter, which is deprecated.". Which is very weird because I didn't used "next" parameter. But when I set next to undefined, it works fine, I get the window, but it says "Given URL is not allowed by the Application configuration.". Expect from that, I can login, then I've got the access_token. But in the new window, getLoginStatus still doesn't do anything.
So any advices are welcome.
Thanks,
Tamas
UPDATE:
function onBodyLoad() { //on body onload
FB.init({
appId: window.appID,
status: true,
xfbml: true,
cookie: true,
oauth: true,
channelUrl: 'http://example.com/fb/channel.html'
});
}
...
function getName() { // on button onclick
FB.getLoginStatus(function(response){
if (response.authResponse)
{
window.loggedIn = true;
debugString('Logged in');
} else
{
window.loggedIn=false;
debugString('Not logged in');
}
}, true);
if (window.loggedIn === undefined) {
debugString('getLoginStatus did not exec'); // I always get this message
}
}
UPDATE 2: I created a new App on a different URL, which is configured as a standalone website. There these codes work perfectly, I can getLoginStatus, I can login, etc. Is there any difference working in the context of FB, and in a standalone website, using FB JavaScript SDK?
FB.getLoginStatus does not fire the callback when you are running the website on a different domain than the one that you registered the app with. I usually find myself in this situation when I am developing locally or on a staging server.
For example, if you registered the site with example.com and your staging server is example.mystagingserver.com, the callback wont fire. In this case, you need to create a second application in Facebook and use the Application ID and Secret for the new app.
I just had the same problem, though it only happened to some users.
I finally found out that if your app is sandbox mode, none-developer users can still see your app as a pagetab. But calling getLoginStatus will fail silently (even logging turned on).
Took a while to figure that one out, I hope this can save someone else some time.
I'm using this code, successfully. I'm not quite sure where the differences are.. but I'm using the ASYNC FB Loader.
window.fbAsyncInit = function() {
FB.init({ appId: 'XXXXXX', //change the appId to your appId
status: true,
cookie: true,
xfbml: true,
oauth: true});
function authEvent(response) {
if (response.authResponse) {
//user is already logged in and connected
FB.api('/me', function(info) {
login(response, info);
});
} else {
//user is not connected to your app or logged out
button.onclick = function() {
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function(info) {
login(response, info);
});
} else {
//user cancelled login or did not grant authorization
}
}, {scope:'email,rsvp_event,status_update,publish_stream,user_about_me'});
}
}
}
// run once with current status and whenever the status changes
FB.getLoginStatus(updateButton);
FB.Event.subscribe('auth.statusChange', updateButton);
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol
+ '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
function login(response, info){
if (response.authResponse) {
accessToken = response.authResponse.accessToken;
userid = info.id;
userInfo.innerHTML = '<img src="https://graph.facebook.com/' + info.id + '/picture">' + info.name+"<br /> Your Access Token: " + accessToken;
}
}
You can use the following code to check if the user is logged in:
FB.getLoginStatus(function(response) {
if (response.authResponse) {
// logged in and connected user, someone you know
} else {
// no user session available, someone you dont know
}
});
From FB JS SDK Documentation.
You can wrap the whole code in jQuery ready :
$('document').ready(function(){
... above code
})
Also you may want to check this question StackOverflow.
I had the same problem. I was working on the facebook login process of our website. During development the "FB.getLoginStatus" did not return a response. I fixed it in the settings of the app on facebook:
-In facebook go to "manage apps"
-Go to the "facebook login" settings of your app
-Add your development url (for example "https://localhost") to the "Valid OAuth Redirect URIs"
(Don't forget to remove the "https://localhost" from the OAuth Redirect URIs when you are finished with developping.)
Something common that causes this is that a browser is blocking cookies, this will cause the event not to fire. Also, make sure that if you or your user have and ad blocker that it is not blocking third party cookies.
Example of warning:
For me after extensive testing can confirm the dialog to log the user will not show unless you use a valid Application ID
These can be found in
https://developers.facebook.com/apps/{{Application__Id}}/settings/
Just make sure you call the api with the correct ID.
How do I implement a Facebook authorization? I have no idea where to start. I have seen numerous examples in PHP but none in C#.
Start here: http://developers.facebook.com
If you can use the Facebook javascript sdk (Much easier IMO, and you have asp.net as a tag so i am making assumptions) you could try something like this:
//Facebook iFrame include
window.fbAsyncInit = function () {
FB.init({ appId: YourID, status: true, cookie: true, xfbml: true });
FB.Canvas.setAutoResize();
authorize();
}
/*
* Facebook Authorization
*/
function authorize (){
FB.getLoginStatus(function (response) {
if (response.session) {
// logged in and connected user, carry on
} else {
// no user session available, Lets ask for perms
FB.ui(
{
method: 'permissions.request',
perms: your permissions
},
function (response) {
if (response && response.session != null) {
//User accepted permissions
} else {
//User did not accept permissions
}
});
}
});
}
